ASH-HANDLING EQUIPMENT.

Application filedJanuary 10, 1927. Serial No. 160,241.'

My invention relates to improved ash handling equipment, and the objects of my improvement are, first, to provide means for utilizing the chimney draft to eliminate dust and fumes incident to ash removal; second, to provide an ash container, .with means for depositing ashes in ash pitor the like without dust; and third, to afiord means for the escape via the chimney of gases arising from any partially consumed fuel in the ash. Y I attain these objects by the mechanism illustrated in the accompanying drawings,

, in which V Figure 1 is a vertical section on line A A in Fig. 3, showing the container and the hood separable; Fig. 2, a plan view of the type of hood shown in Fig. 1; Fig. 3, a vert-ical elevation, partly in section, of the hood shown in Fig. 1; Fig. 4, a vertical elevation, partly in section, of an alternative construction in which the hood is fixed to the container; Fig. 5, a plan view of Fig. 6'; Fig. 6, avertical section on line B B in Fig. 4; Fig. 7 a fragmentary sectional elevation on line C C inFig. 2.

Although a I show the preferred 'GIIIIJOdi-r ment of my invention, I do not thereby limit myself to the precise form shown, but wish it understood that various changes in the details of construction may be made within the scope ofthe claims.

Like numerals refer to like parts throughout the drawing. 5

The container A comprises cylindrical shell 1 having slot 6 in its lower edge to which is fixed bottom 2 having opening 3 therein, annular conical shell 1 disposed within shell 1 with its smaller opening concentric with opening 3 and its lower edge in close' proximity to bottom 2, a slidable plate 5 disposed on said bottom and extending through said slot; and handles 7 and 23.

For the type of equipment wherein container and hood are separable hood B comprises plane circular sheet 8 having de- 7 pending rim 9 and a rectangular opening over which is fixed rectangular shell 10 having an open end in which plate 11,.oontaining slot 12, is vertically hung from hinge 11*, so as to permit its being swung inward or outward as indicated by dotted outlines in Fig. 7; a'pan13 fixed to sheet 8, and.

handles 14.

Thimble 15 is mounted on shell 10 and is in open communication with interior of hood B; pipe 18, having angular slots 19, in which thimble 15 is movably. mounted, is in open communication with chimney flue, via smoke pipe 20 damper 16, mounted on shaft 17, the ends of which project-through slots 19,is disposed in thimble 15.

'For'the type of equlpmentwherein container and hood arenot separable, the hood comprises plane circular sheet 8 fixed at lts outer edge to container shell 1*, and having a rectangular opening roverwhich is fixed rectangular shell 10* having an open end over which plate ll provided with handle 24, is hung from hinge 11, so as'to permit its being swung outward andupward as indicated by dotted outline in Fig. 6.

Thimble 21, fixed on upper face of shell of hood 0; pipe 18 is fixed to and is in open communication with smoke pipe 20; damper 16, ,mounted onshaft 17 is dis.- posed within pipe 18% sleeve 15*, provided 10*, is in open communication with interior with handles 22 and angularslots 19 is slidably mounted on pipe 18 and detachably' connected with thimble 21.

In; operation, damper 16 is opened and ashes then shoveled into container A through opening in hood B. Plate 11,

pushed inward as theshovel enters, returns to a vertical position with the shovel handle in slot 12, and as the shovel is withdrawn swings outward. Dust and gas from the ashes escape into the chimney via thimble 15 and pipes 18 and 20. As damper 16, which is then shut, does not entirely close pipe 15, gases from partially consumed fuel in the ash escape via thimble 15 and-pipes 18 and 20 into the. chimney.

Pan 13 is designed to catch any ash dropped from shovel.

filled hood B is lifted Then container is and turned until the projections ofdamper shaft 17 enter the horizontal sections of an gular'slots 19. Container may then be removed, placed over an ash pit or the like, plate 5 withdrawn by means of handle 23, and the ash precipitated into pit.

With the alternative construction shown,

wherein the hood and container are integral, the operation differs from the above in that cover ll" is opened to position indicated by dotted outline in Fig. 6, the ashes shoveled into the container and cover ll closed. lVhen container is filled, sleeve 15 is lifted and turned until the horizontal sections of angular slots 19 are entered by the pro jeetions of damper shaft 17*, thus detaching container.

hen the containers are being emptied, an

ordinary lid may be used to cover the open end to prevent the escape of ash dust.

I claim:
